I don't know what DJI's on about with regards to your claim.
I've seen them replace several that appeared to show the same symptoms.
If they are telling you that flying at 240 feet over a bakery would create those symptoms and cause the Phantom to zoom away like it did, I'd say that's a load of bunk.
If that did cause some interference, then why didn't the Phantom just come home rather than zipping away at high speed.
The DJI story as you've reported just doesn't add up.
I don't know what you should do except perhaps appeal to DJI-Ken over on the DJI forum and ask him t have a look because the explanation you've been given doesn't make any sense.
To all those that are certain that Autel must be the next best drone and is going to blow everything else out of the water etc etc ..
Most of the folks here (the kind of people you refer to as
youtube dji lover boys) already have a P3 and are simply interested to find out what the grass is like on the other side of the fence.
A lot are keen to jump aboard the next best thing when/if it comes along since the P3 has been out for almost 1.5 yrs now.
Since we already have a Lightbridge P3 or 4 we want to know what the X-Star does better than DJI's product to decide whether it's worth buying.
Because there are so few X-Stars out there, actual information from users is scarce and quite a bit of what there is, is either uncritical marketing or uninformed comment from users with no or little experience of the competition.
This is about the best summary/comparison I've seen so far:
Third hand comments like
I think that 70% of them will say that they prefer the Autel of the P3 pro .. or unsubstantiated
it flies better, camera is better comments aren't going to be blindly accepted by people looking for facts.
We've seen over-hyped new drones come and go (or in quite a few cases, not come at all).
Think 3DR Solo, Yuneec Q500, Walkera H500, Prodrone etc, etc.
The X-star is just the latest to come along (congrats to Autel for actually getting their drone to the market when so many have failed at that.
Think Lily, GoPro Karma, Plexidrone, Prodrone etc, etc.
If you already have a Lightbridge P3/4 you are naturally going to critically compare the way the newcomer compares.
So far as best I can work out, the X-Star Premium is a reasonable match for something between the P3-4k and the P3 Pro.
It's camera is reasonable if the lens distortion doesn't bother you and the image quality is similar.
It flies slower and has a little less range than Lightbridge, but with more lag.
There are enough comments from actual Lightbridge/Autel users to work that much out.
On the plus side it's camera comes off at the touch of a button (?) and it comes in orange.
For those with a dislike of DJI, it's an alternative.
We'll see when/if that happens but there's not much point discussing that now.
We may not be interested in how it compares to the P4 by then.
DJI or someone else might have delivered something even better by then.
